Some packages you might be interested in:

ip-acct
nacctd

in case of http traffic, you have squid which is a full blown proxy
server that not only tracks the urls clients in the network are
accessing, but also caches data that is being requested.

in the case of actual connections, you could run iptraf from the
gateway of the network, to see where the internal nodes have been
connecting to, and what kind of packets are passing through your
network. however, a word of caution, if you're not very experienced or
knowledgeable in network administration or TCP/IP networking in general,
it may be overwhelming.

some playing around with it should be helpful.

ntop - http://www.ntop.org/ntop.html
ntop has been designed to be simple, performant and easy to use. It has been developed, tested, and deployed by a large user community on various networks and environments. In some environemnts, ntop is not enough as it lacks some features needed by power users.

mrtg - http://people.ee.ethz.ch/~oetiker/webtools/mrtg/
The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network-links. MRTG generates HTML pages containing graphical images which provide a LIVE visual representation of this traffic. Check http://www.ee.ethz.ch/stats/mrtg/ for an example. MRTG is based on Perl and C and works under UNIX and Windows NT. MRTG is being successfully used on many sites around the net.

Those tools you also can consider, but as shivsa suggest iptraf is a good tool, but it's a console-base program.

IPTraf is console-based network statistics utility for Linux. It a variety of figures such as TCP connection packet and byte counts, interface statistics and activity indicators, TCP/UDP traffic breakdowns, and LAN station packet and byte counts.

Snort - http://www.snort.org/
Snort is able to analyse IP traffic and provides very strong logging.
It relies on rules scripts, that is you can monitor what you want to. Even more, the snort site provides you with a rules database.

Also have a look here to see this can give you some idea http://www.tldp.org/linuxfocus/English/January2001/article180.shtml#lfindex0

Of all of these MRTG is the best of the packages that I've used. I have used it to monitor 90+ servers for bandwith spikes and other data to find patterns for attacks/DDOS .

Snort is best used for the anaysis of the data.
